This should be an easy one. It's obviously an electrical problem. Do you have access to a VOM? (Volt Ohm Meter). With the bike off, you should have 12 volts at the battery. With the bike running, you should have at least 14 volts at the battery. Are the connections to the battery tight and corrosion free? Just because you have a new bike, that doesn't mean that possibly the cables have corrosion or the battery is bad. Happens all the time. I don't think this would be it (Honda's have awesome quality control, but even the best slips up from time to time!) but the alternator has an internal voltage regulator. It may be bad.
The easy fix is to take the bike in. I too, have an extended warranty, and I won't do anything but chain adjustments myself. That's why you paid the big bucks! Bring it in, describe your problem, and let them deal with it. They have the test equipment, reference materials and the money to fix whatever they toast. Check the cables and stuff and if that doesn't work, take it in. If you screw something up, your warranty is toast.
